LSH-P moon mode? Hmmm...

voodoogreg · Dec 22, 2004

I have gone through about 4 batt's in my ARC LSH-P. i seem's to be bright for a good long while and then a bit of deline to low. I have never seen it go into "moon mode" (blink, then drop in power as stated in the manual).
Is this normal? the other one my guitar tech has so i don't know about that unit, but mine I have not seen this blinking. VDG

I noticed the same on my LSH-S... No bright/dark - just getting gradually darker. i'm using alcalines

As with a lithium 123 it runs long, then drops semi quick. thn get the gradual dimming. yep sounds like Std thing to me, thank's and have a happy holiday's BBL! VDG

From experience, I'm guessing that your led is probably high vf so the light is running semi-regulated. If this is the case, the dimming will be so gradual you won't notice it with the naked eye. My LS used to behave this way until I swapped out the led with a TWOH then the transition to moon mode became very noticeable. It drops to dim from very bright.

So is that good or bad? /ubbthreads/images/graemlins/grin.gif actually I would agree in the dimming,, not till it's noticeable,,uh,, do i notice it to be dim. I really am really kinda glad it doesn't dive bomb into moon, I rather a light dim slowly. VDG

Good or bad depends on personal preference.

Since I prefer fully regulated, I want the light to be as bright as can be for as long as possible before suddenly going extremely dim.

With semi regulation, the dimming is more gradual so you won't experience sudden dimming of the light.

In terms of efficiency, lower vf is definitely better as it will consume less power overall resulting in cooler running and longer runtime.
